You're not giving anybody any useful information to help you. What is the reason given in the 550 rejection? You really ought to paste the full SMTP dialog [after editing the specific items that reference your server and email accounts so that you don't reveal it in the forums].

Gmail is pretty good about giving a decent "reason" for a 5.5.x rejection that should give you a clue why it's being rejected.
